One way would be to graph the equation.
Another would be to rearrange the equation to:
$${\mathtt{y}} = {\mathtt{\,-\,}}\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{16}}$$
The x-intercept occurs when y=0
The y-intercept occurs when x=0
